On Sunday's new episode of WAGS, new WAG Michelle Quick gives Natalie Halcro and Olivia Pierson a very unfriendly welcome to Amber Nichole Miller's party.

Michelle's resentment stems from a past incident where she claims Nat and Liv were rude to her. As soon as Nat and Liv arrive to the party, Michelle quickly brings up their bad blood.

"Now that we're all here together, last time I saw you guys it was kinda funny, so I just want to make sure we're all on the same page," Michelle tells the girls. "So it wasn't very tasteful what happened last time."

"How I remember it was you were rude and you made a really negative comment actually," Olivia tells the group.

After Olivia enters the conversation, Michelle flies off the handle and accuses her of butting in to defend her cousin. Then Olivia calls Michelle plain "rude" and Michelle replies, "I mean, I don't really know you."
